Not without upgrades
AS an owner of a 1977 C-30, I'd be very apprehensive about bluewater cruising unless I put some upgrades into her. The chainplates (especially the starboard side) would all need to be beefed up & I'd take a close look at the rudder, rudder post & steering assembly for starters. If you have original thru-hull fittings, those will have to go, too. Obvious stuff, like water storage, fuel capacity, etc, should also be looked at. All in all, the boat wasn't designed for that kind of use, but upgrades will get her up to speed. I've read that others have taken their C-30's accross oceans, so I know it can be done, I'd just be certain you've considered every detail before heading out.
